INTEGRATED MODULAR REFRIGERATION SYSTEM This invention relates generallyto quick freeze refrigeration apparatus which is adapted for use aboardship for freezing shrimp, fish and the like and which is particularlydesigned to consist of modular units adapted to be functionally attachedtogether with an insulated framework. The apparatus is designed to beattached to the deck of a ship and provide communication between thedeck and cold storage hold. The unit is further designed to be attachedto any convenient part of the deck with only slight modification and theunit will not cover or occlude any existing hatchways.

Large scale shrimping operations are carried out by trawling boats whichstay out collecting shrimp until they get a full load. The period oftime these trawlers spend out of port depends upon the luck of the catchand the distance that must be traveled to the shrimping grounds. In thepast, shrimp trawlers were forced to stay relatively close to a portwith a processing plant because of the tendency of shrimp to deterioraterapidly. In order to slow down this deterioration, ice is used to coolthe catch. The general practice has been to place the ice and shrimp inlayers into some sort of container such as a barrel. Along with thewaste of time and manpower which is inherent in an operation of thistype, the weight of the ice and storage space required for an extendedtrip makes the cost of this method prohibitive, especially in view ofthe fact that ice is not very effective as a preservative. It has beenfound that although ice tends to slow down the deterioration of theshrimp the bacteria count per unit time rises rapidly with cooled, butnot frozen, shrimp. Further, just cooling and not freezing shrimp tendsto make the shrimp bodies soft and hence subject to be easily damagedduring storage at the bottom of a barrel, or during unloading andhandling before processing. Because of this easy spoiling tendency it isnot unusual for a trawler to have 5-10 percent of its catch rot by thetime the shrimp reach the processing plant. In addition to rotted shrimpanother problem is the tendency of shrimp to develop black spot. Thisdiscoloration on the body of the shrimp does not effect the edibility ofthe shrimp but, because of the appearance of shrimp affected with blackspot they are practically worthless in the consumer market. Thisdiscoloration of the shrimp is caused by an enzyme action which isslowed down but not stopped by cooling the shrimp with ice. In order tostop this action even further, it is necessary to quick freeze theshrimp.

It is desirable then, in view of the above, to do away with icing as thepreserving medium and replacing it with some sort of mechanicalrefrigeration system. Several mechanical refrigeration systems have beendeveloped but most of them are too costly and complex to justify beingused on the small shrimp trawler. For instance, in one prior art system,the shrimp are placed through a loading hatch into one or more storagetanks in the hold. Brine is then circulated by pumps, and then siphonedoff when the trawler reaches port. As can be seen, this calls forcomplex structural modification of the trawler and would be tooexpensive and complex for the small boat.

Presently, there are numerous different types of quick freezerefrigeration apparatus available, however, all are generallyunsatisfactory for use aboard fishing boats, for one reason or another.For example, see U. S. Pat. No. 1,912,896 to Hiller. The apparatus ofthis patent employs freezing sea water and a plurality of brine tanks soarranged that the freezing brine of any one tank after its use has beendiscontinued may be utilized to partially cool the brine beingintroduced in any other tank. It is readily apparent that this apparatusis generally inefficient and, furthermore requires a complex, bulky,substantially permanent installation. Accordingly, it objectionable fora number of different reasons.

In U. S. Pat. No. 2,059,970 to Robillard, quick freeze refrigerationapparatus is disclosed wherein the shrimp or fish are rapidly cooled andfrozen by contacting them directly with a volatile liquid refrigerantwhich is vaporized, recondensed, recovered and used over again. Acontinuous belt conveyor is used to transport the shrimp and fishthrough the volatile liquid. In viewing the drawings of the subjectapparatus, it is apparent that it is far more complex, bulkier and moredifficult to install than the above-described Hiller apparatus.

Still additional quick freeze apparatus is disclosed in U. S. Pat. No.2,077,607 to Wood. With this apparatus, the articles are frozen by aflow, blast or accelerated current of air or other aeriform fluidreduced to a temperature not higher than zero Fahrenheit. The apparatusgenerally is not adapted for shipboard use.

U. S. Pat. No. 2,513,004 discloses a ships hull construction having alarge number of compartments or containers in which shrimp or fish areretained. A refrigerant is circulated around the compartments orcontainers in conductive contact with the shrimp or fish. Similar large,complex installations in ships are disclosed in U. S. Pat. Nos.2,746,272, 2,909,040, 3,049,890 and 3,261,176.

Still other types of quick freeze refrigeration are available which usea solution of salt and syrup to quick freeze the shrimp or fish. In mostcases, the apparatus has a construction such that the solution can spillout of it, generally on the crew or deck. This is not only messy andpresents a safety hazard, it also is a waste of solution. Others usebaskets which must be lifted in and out of the tank in which thesolution is retained and/or have heavy lids to open and close. This typeof apparatus is very inconvenient and its operation is time consuming.In addition, they are very dangerous since it is extremely difficult tohandle the baskets and the heavy lids in a rolling sea. Sucharrangements have cost more than one man his fingers and hands. Stillother apparatus is complex in operation and/or requires considerabledeck space for its installation which, in many cases, is furtherobjectionable because it is a permanent or semi-permanent installation.

An object of the present invention is to provide improved quick freezerefrigeration apparatus.

Another object is to provide a quick freeze system which consists of aseries of modules which are adapted to be separately replaced, quickly,if one fails.

Still another object is to provide improved quick freeze refrigerationapparatus of the above character which is particularly adapted for useaboard fishing boats.

A further object is to provide improved apparatus of the above characterwhich can easily be affixed over a special hatch of a fishing boat.

A still further object is to provide improved apparatus of the abovecharacter which has a construction such that the solution therein isprevented from slopping out of it.

Another object is to provide apparatus of the above character which doesnot require the handling of baskets in and out of a tank.

Another object is to provide apparatus of the above character which isof a construction so as to save deck space.

Another object is to provide apparatus of the above character which isfurther adapted to refrigerate the hold of a fishing boat.

Another object is to provide apparatus of the above character which isrelatively simple in construction and requires little maintenance.

Other objects of the invention will in part be obvious and will in partappear hereinafter.

The foregoing and other objects of the invention not specificallyenumerated are accomplished by providing a quick freeze refrigerationapparatus which is of modular construction that is adapted to fit over aspecial hole or hatch on the deck of a fishing trawler. The apparatus isof a compartmental design wherein some compartments are covered byintegral insulation. The individual modules are placed in a frameimbedded in the deck of a trawler and adapted to be removed and replacedwith ease in the event of a break down of one units. The various modulescomprise a first module including cooling coils and blower, a secondmodule including a quick freezing means and conveyor, and a third moduleincluding a compressor and motor.

In operation, the compressor and motor circulates cooling fluid in aseries of coils located in the quick freezing and conveyor module. Thequick freezing and conveyor module comprises a freeze solution, a pumpto circulate the freeze solution around the cooling coils and a conveyorto remove the frozen shrimp from the module and place them into the coldstorage hold of the vessel. The cooling coil and blower module is thesection of the unit concerned with keeping the cold storage hold at alow temperature. The cooling fluid from the compressors is run through aseries of coils and the associated blowers are adapted to withdraw airfrom the hold, pass it over the coils and reinfect the colder air.Further there are associated with this module doors that when openedwill draw air from the outside and insert this warm air into the holdthereby aiding in defrosting of the unit.

In a modular unit of this type the modules need not physically abut eachother but may each be placed at different locations depending upon thedesign of the trawler. For instance, all the ship builder needs is theframe for the particular configuration of refrigeration unit that willbe used on the trawler. After completion of the vessel the modular unitmerely needs to be placed in the frame and connected.

These refrigeration units are designed to freeze the shrimp catch of thetrawler from 80 to 100 feet and to keep the holds, which are up to 3000cubic feet, cold for protracted period of time. These units are verylarge, here, all three modules are approximately 8 by 8 by feet andweigh several thousand pounds. Because of their size there has been aproblem in shipping these units from the point of manufacture to thesight where the unit is being built into the trawler. This modulardesign not only allows the ship designer to place the parts of the unitmore efficiently, but the individual units are much easier to ship andto handle.

The invention accordingly comprises the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth and the scope ofthe invention will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention,reference should be had to the following detailed description taken inconnection with the accompanying drawings in which:

FIG. 1 is a bottom perspective view of the modular unit.

FIG. 2 is a top perspective view of the modular unit without the top andside walls.

FIG. 3 is a cross-sectional view along line 3-3 of FIG. 2.

FIG. 4 is a cross-sectional view along line 4-4 of FIG. 2.

FIG. 5 is a frontal exploded view of the modular unit. Similar referencecharacters refer to similar parts throughout the several views of thedrawing.

Referring now to the drawings, in FIG. 1 there is shown a perspectivebottom view of the modular quick freeze apparatus 10 which is designedto be built or installed into the deck of a shrimp trawler. As shown inFIG. 5, the frame 12 is separate from modules 14, 16 and 18 and isadapted to be placed in the deck of the ship during or afterconstruction. The cool air exhaust louvres 20 or doors (not shown) areshown on the bottom of the frame. These louvres or doors providecommunication between the cold storage hold of the vessel and thecooling coils and blower module 16 and can be selectively operatedindividually or in combination.

More specifically, the quick freezing module 18 is substantiallyrectangular shaped with a top wall 22, a bottom wall 24, and side walls25-28 so as to provide a container through which the freeze solution canflow. Referring to FIGS. 2 and 4, within the quick freeze module 18, isshown a lift pump 30 consisting of a lift tube 32 which is open at thebottom and the top end. A motor 34 drives a shaft 36 and an impellerblade 38 within lift tube 32. A spill tray 40 is attached to the opentop portion of the lift tube 32 and is adapted to spill the freezesolution through filter screen 42 and into the quick freeze area. Screen42 acts to prevent any of the comestibles in the quick freeze area frombacking up into the lift pump mechanism. The quick freeze area of module18 is defined by screen 42, side walls 26 and 28, a cooling plate cover44 and the conveyor belt 58. A second filter screen 48 is also providedto catch any shrimp pieces that may pass conveyor 46. Beneath coolingplate cover 44 are located a plurality of cooling plates 50 in a fixed,spaced, parallel relation to each other. The cooling plates are coupledto a compressor module, discussed below, and are cooled by thecirculation of a cooling fluid within each of the cooling plates. Anendless conveyor 46 is also located within the freezing module 18. Theconveyor is rotatably supported on a pair of rollers. Roller 54 has amotor 56 affixed to it for rotatably driving the roller 54 and the belt58 of the conveyor 46. Belt 58 is preferably made of mesh of some typethat will pass liquid but will retain the shrimp. Conveyor 46 isangularly disposed to and partially submerged in the brine, freezesolution and functions to lift the frozen shrimp out of the brine anddeposit the shrimp into a drop chute 60 which is positioned to spill thefrozen shrimp into the cold storage hold of the shrimp trawler. Thefreeze solution in the module 18 is preferably a solution of corn syrup,salt and water which has been found to be exceptionally satisfactory toquick freeze shrimp placed within module 18 through a suitable intakechute such as shown by chute 62 in FIG. 1. Other solutions, however, canbe used and for the purpose of the invention, it is only necessary thatan appropriate solution for freezing the shrimp be contained within themodule 18. The temperature of the solution is thermostaticallycontrolled to prevent the solution from freezing up and seperating. Thecoils keep the solution cooled to approximately minus or 12 F. Heattransfer is designed to provide a freeze production rate of 500 lb/hr.On a continuous basis. Circulation of the solution is-established andmaintained by the lift pump 30 which lifts the solution from the bottomof module 18 and forces it out over spill tray 40, through screen 42,conveyor web 46, second filter screed 48 and around the parallel,spaced, cooling plates 50, as the solution flows around cooling plates50 the heat picked up by the circuitous travel is dissipated into theplates. In use, the shrimp are dumped into intake chute 62 and spillinto the freeze solution. Deflector 43 is provided to insure none of theshrimp fall into the motor workings of lift pump 30. The circulation ofthe solution keeps cold solution in constant contact with the shrimp andalso moves the freezing shrimp to the right. The shrimp are retainedwithin this freezing compartment until frozen which generally takesabout 10 minutes. When the shrimp are frozen they will rise to the topof the brine solution and will float against the conveyor. The conveyor46 is then activated and lifts the shrimp out of the solution. At thetop of the conveyor 46, the shrimp can be packed, boxed, or packed inbulk to be taken to the refrigerated storage hold below deck.Alternatively, the shrimp can be spilled off the conveyor 46 intothedrop chute 60 and deposited in bulk in the hold.

The modular quick freeze apparatus 10 is further adapted to refrigeratethe cold storage hold of the vessel. For this purpose, module 16 isprovided. The module is generally rectangular coil shaped and isprovided with a top wall 64, a bottom wall 66 and side walls 67-70 so asto provide an insulated enclosure through which cold air can flow.Within module 16 is affixed a convoluted brine or cooling coil 72 asseen in FIGS. 2 and 3. A pair of openings 74 and 76 are located at eachend' of bottom wall 66. These openings 74 and 76 provide pneumaticcommunication either directly or through tubular duct 78 with the coldstorage hold. Several louvred openings 20 or doors "(not shown) arespaced around the cold air duct 78. FIG. 1 illustrates the arrangementof the duct and louvred openings in frame 12. A blower 80 is mountedover intake opening 74 such that when blower 80 is actuated by motor 82,attached to bottom wall 66, air from the cold storage hold will be drawnup, blown across cooling coils 72 and forced back down into the coldstorage hold through exhaust opening 76. The air within the cold storagehold is then constantly circulated and cooled by module 16. A pair ofdefrosting doors 84 and 86 are provided on side walls 67 and 69respectively for defrosting cooling coils 72 and the cold storage hold.When the openings 74 and 76 are closed and the defrosting doors 84 and86 are open, ambient warm air will circulate about the cooling coils 72.When it is desired to defrost the cold storage hold itself, exhaustopenings 76 as well as defrosting'doors 84 and 86 are uncovered and theblower forces warm air into the cold storage hold.

Thecooling plates or coils 50 and the brine coils 72 are coupled to andcooled by a refrigeration module 14, which is generally rectangularshaped and has a top, bottom and four side walls 87--92 respectively.The module contains the engines or motors 94, compressor and condenserunits 96 to cool the freezing fluid.-

The module units may be constructed of plastic, fiber glass or type 316stainless steel or other materials with durable welded, bolted or gluedseams and joints. The freezing and cooling modules 16 and 18 areinsulated with insulation material such as Dow Chemical urethane, 3inches thick or more. The brine coils 72 are type 316 stainless steeltubing or its equivalent which are V2 or 1 inch outside diameter. Allbrackets, clamps, surface extenders or other braces also are plastic,metal or type 316 stainless steel and are welded or bolted to themodules 14, 16 and 18 and frame 12. Electrolytic or galvanic action isthereby maintained at nearly a zero reading.

It is also within the contemplation .of this invention that variousmodules 14, 16 and 18 be installed in different locations on the shipinstead of all together as illustrated. The module could also be placedtogether oriented differently from that shown, for instance modules 14and 16 can be installed end wise or in some other position in order toconserve space on the ship deck.

It will thus be seen that the objects set forth above, among those madeapparent from the preceding description, are efficiently attained and,since certain changes may be made in the above construction withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawing shall be interpreted as illustrative and not in a limitingsense.

It is also to be understood that the following claims are intended tocover all of the generic and specific features of the invention hereindescribed, and all statements of the scope of the invention, which, as amatter of language, might be said to fall therebetween.
